To all whom it may concern.'

Be it known that we, NORBERT Koen, res1d1ng at EssenontheRuhr, Germany, and

GEORG HAYN, residing at Essenonthe- 5Ruhr, Germany, both subjects of the Emperor of German have invented a certain new and useful mprovement in Barrel-Recoil Guns, of which the following isa spci-4 fication.

The present invention relates to barrelrecoil guns and theobjcct of the invention is to provide a barrel-recoil gun which, while having a small firing height and having the mount and its support subjected to the smallest strain possible, permits of the highest elevations occurring 1n practice being 1mparted to the gun-barrel.

The invention consists in a barrel-recoil gun whic is constructed to permit loadin to take p ace'jn the position of recoil an( firing to take place during the return movement of the 11n-barrel and in which the axis, about which the gun-barrel swings during the elevation, is located in the proximity of the breech of the gun-barrel when the latter is in the position of recoil.

In the accompanying drawings the invention is shown ap hed to a gun with pivot- |nount,`l5 v way ofp example.

Figure l is a side view of the Iun mounted on an automobile; Fig. 2 is a si( e view, on an enlarged scale and partly in section, of the slide-track carrier and the gun-barrel, the

\latter being shown in its foremost osition;

Fig. 2a is the other side view* of t e arts shown in Fi 2 and of the means for in the gun and o recoil Fig. 3 is a. section on line 3-3, Fig. 2,

looking from the right; Fig. 4 is a 'section on 4o line 4--4, Fig 2, looking from the right, and

Fig. 5 is a rear View, partly in section on line The pivot-support A of the gun is mount ed on a platform which is carriedby the frame B oi an automobile, In the support A the biurcated upper carriage C 1s rotatably mounted through the medium of a vertical trunnion (not shown inthe drawings). A horizontal training mechanism of 5o known construction and having a handwheel D is inserted between the ulptper car-V riage l and the support A. The s e-track carrier E El, whic guides the gun-barrel F during the recoil and return movement, 1s swinglngly mounted in the upper carnage C r retaining it in the position o I ahrou h the medium of horizontal trunnions l e slide-track. carrier is composed of two parts one of which (E) is located below the gun-barrel while the other (E) is located above the n-barrel. A U-shapadpuget:- txon es (see 1n particular Fig. A) provid' 'on the part E embraces the ln-barrel-and is rigu y secured to the part and serves for connecting the two pIartsE and E 0f the slide-track carrier. he relative a ment of the parts E E1 and 4pro'oction il selected in such amanner tha thewslido track carrier is substantially step ,od-shape.

The part E carries on its free en tihonzontal trunnions eand is'adapted to guide the brocchrFl of the gambaml. For that pur ose the part E is rovided with a slide? trac e (Figs. 2 .an 5) for two raillf' mounted on the breech F1 and with twg claws e which overlap the rails f. slide-track e* and the claws c extend over the entire length 0f the part E; Tho put E* contains a recoil-brake of lknown construe tion and aV temperatur-spring G (Figs. 3 and 4) which surrounds tha cylinder H of the n coil-brake. The cylinder H is secured to o horn son the breech F1. ThopartEis Il vide with two guide-claws c' 'which 'e throu hout its length and with whichV K rails i a'rra ed on a 9 Secund on" gunarl-el.

The horizontal trunnions l are arranged in such a manner that the are located 1n the roximity of the breech li when the latter is in the position of recoil. This arrangement makes it ossible, while having the firing height of t e gun comparatively low, to impart to the gun-barrel any desired elevation that can occur in practice and to'load the gun at such elevation of the barrel (compare the position of theparts shown in dotted lines in Fig- 1).

Attention is further drawn lto Athe fact that the e* e! c of .the slide-track carrier and the guides f j1 'of the gun-barrel,which are adapted to engage with the Aguides on the carrier, areA errang in such a manner that they with'each other at any; position of the gun-barrel relatively to t e track- In this wa the gun-barrel is guided as securel as possi le;-

A'When t e gun-barrel during `the transport of the gun, assumes the osition shown in Fig. 2 relatively to the the gun-barrel is, before the first shot is fired,

drawn back into the position of recoil shown m Ifthrouh the medium of the aforesaid evice (rac and pinion) and is secured in' thatv sition b -means of the latch e" entering t notch of the breech end. `The gun is thereupon oaded and ointed and the v 5mi-barrel is subsequently re eased by with- 35 rawin the latch e" and moves forwardly under t e action ofthe recuperator-spring. During the forward movement of the dgunbarrel the gun is automatically fire by means of the trier j? strikin the nose e. After the gun is ed the reco' takes place, the energy of which is partially absorbed by the ener of the forwardl moving gunbarrel. he remainder of t e recoil-energy is partially' taken u by the recoil-brake and by the friction. in t e guides, etc., and partially stored in the recuperator-s' ring. However therecoil carries the gunarrel backY into the position shown in Fig. 1 in which lpositiolifthe gun-,barrel is automat- *ically secured bynieans; of4 the latch el.

After the n hasbeen loaded afresh 'and the gun-barre isreleased the operationv is `reated in the aforesaid manner.f As above stated a part of therecoil-ener y is absorbed by the energy of the forward y moving `gurbbarrel andt e resistance in the .brakeand in the recuperator need therefore 'z onl be small Iand. thegun-barrel can neverthe ess have a. relatively short recoil. A small resistance inthe brake etc., permits of the gun-carriage being of light construction without endangering the stability of the marriage, While ashont recoil permits of gre at elevations bein' im arted to the gun while having the ,firing ieight small. Furtheride-track carrierf iafioa more by having the horizontal trunnions arranged in the proximity of the breech when the latter is in the position of recoil it is ossible, 'inspite of a small liring height, to impart to the' iin-barrel any desired elevation and load t 1e un at any elevation. By 4reason of the com ination of these roperties the improved gun presents a hting medium suited for mountm on light vehicles on land and water and w ich is especially serviceable against airships. A

The invention is of course equally adaptable, to guns with wheeled mount.
